Abstract (en)

[origin: WO2015036882A2] A water-based lithium ion battery cathode slurry comprising a cathode active material comprising a lithium transition metal oxide powder wherein the lithium transition metal oxide powder consists of agglomerates of primary particles, the primary particles comprising a coating layer comprising a polymer is proposed. The polymer is preferably a fluorine-containing polymer comprising at least 50 wt% of fluorine. The coating layer preferably comprises a first inner and a second outer coating layer, the second outer layer comprising the fluorine-containing polymer, and the first inner layer consisting of a reaction product of the fluorine-containing polymer and the surface of the primary particles. The reaction product preferably comprises LiF.
